VBA File Selection Function: Easy File Dialog Implementation

Looking for a VBA file selection function that simplifies your coding workflow? This practical VBA file dialog implementation makes selecting files in your applications effortless. The function allows users to choose multiple files using a standard Windows dialog box and returns the selected files as an array for easy processing.

How This VBA File Selection Function Works

The VBA file selection function below accepts a filter string (like “*.txt” or “*.xlsx”) and returns an array containing the full paths of all selected files. This makes handling file selection in your VBA projects much simpler and more user-friendly.

'VBA file selection function that returns selected files as an array
Private Function fileList(sFilter As String) As Variant
    'Declare a variable as a FileDialog object
    Dim fd As FileDialog

    'Create a FileDialog object as a File Picker dialog box
    Set fd = Application.FileDialog(msoFileDialogFilePicker)

    Dim i As Integer
    'Use a With...End With block to reference the FileDialog object
    With fd
        .InitialFileName = ActivePresentation.Path
        .Filters.Clear
        'Add a filter that includes specified files
        .Filters.Add "All files", sFilter
        If .Show = -1 Then
            Dim fileData
            ReDim fileData(.SelectedItems.Count - 1)
            'Step through each string in the FileDialogSelectedItems collection
            For i = 1 To .SelectedItems.Count
                fileData(i - 1) = .SelectedItems(i)
            Next i
        'The user pressed Cancel
        Else
            Exit Function
        End If
    End With

    'Set the object variable to Nothing
    Set fd = Nothing
    fileList = fileData
End Function
